Perhaps you should try some spelling variations:
birth timing » burst timing
chinas birth » chains birth, child birth, china north
timing file » timing life, timing family, timing figure
ii chinas » ii china's, ii china, ii chinese
long jin » long run, long did, yang jin
song jin » song min, shang jin, song shin

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong sin) OR (dong di)) ii chinas birth timing file ((long jin) OR (song jin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sin) or (dong di)) ii chinas birth timing file ((long jin) OR (song jin)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong sin) or (dong di)) ii chinas birth timing file ((long jin) OR (song jin)) ;*.
